摘要
以混沌系统中典型映射——Logistic映射作为研究对象,提出了利用混沌理论进行话音加密的算法和基于DSP(Digital Signal Pocessor)平台的嵌入式设计方案,方案中采用TMS320VC54X系列DSP芯片与软件结合,实现了嵌入式结构。设计了标准的异步串行接口,可同多种话音通信终端连接,具有很高的安全性和广泛的实用性。
A kind of typic chaos map,Logistic map,was researched.Chaos theory can be used to encrypt voice digital signal.An embedded module devising plan based on DSP flat was presented.The project adopted TMS320VC54X series DSP chip combining with software technology and realized embedded chaos encryption voice communication system.The system also schemed a standard asynchronism serial interface to connect diversified voice terminals and made it possess high security and broad applicability.
